Gaspari Nutrition SizeOn and Gaspari Nutrition SuperPump250

Introduction: I started to work out at the gym in 2000 and between around that time and 2004, I would routinely use various creatine supplements before writing them off in early 2004 after reading on so many message boards that creatine products as well as other supplements are merely snake oil and offer no effects other than those of a placebo in nature. They explained that the magazines have a vested interest in selling supplements and they therefore cannot be trusted to deliver honest information about the products they help to endorse. This made sense to me so I wrote off all supplements from that point forward and would rarely even use a protein powder after that point.

In 2007, I decided to go to the Arnold Classic expo and check out the professional bodybuilding world on display and while I was there, I asked some of the vendors if they would be willing to give me samples of their supplements for review. There were many free samples being given away, but I decided to ask for full tubs of certain supplements so that I could write more in-depth reviews on them. Many of the supplement vendors gladly fulfilled my request and Gaspari Nutrition was one example who did. The National Sales Manager, Tom, gave me a full tub of SizeOn for review. I had written off any sort of creatine supplement since 2004 and had no faith in it whatsoever. To my surprise, SizeOn worked! Over the month I used it, I put on around 9-10 pounds and most of that size was put on in the first 10 days of use. Of course it would make sense that some [or even most] of that weight was merely water weight, the fact is, my pumps were better than ever and my arms muscles felt harder and fuller than they ever had before. That first experience with SizeOn really renewed my faith not only in creatine products, but in supplements in general, and since that time about two years ago in the Spring of 2007, I have been using various supplements off and on with great success. Yes, it is true that post-cycle you will lose some or even all of your gains, but I find that the psychological edge that supplements give me make them worth it for me to include from time to time, yet I will also be free of supplements for extended periods of time so that I do not develop any sort of tolerance towards them. In the past two years, I have used creatine five times, and SizeOn by Gaspari three of those five times, at this point, trying all of the available flavours [Grape Blast, Arctic Lemon Ice, Wild Berry Punch]. So far every time has been a great success and well worth it. Frankly, I have no reason to try any other creatine product on the market since SizeOn has been so consistently solid for me. Of course since I am in the habit of reviewing as many different products as possible, I will not likely use SizeOn again any time soon, but it is bar none the best creatine blend that I have tried thus far.

More Information on SizeOn

SIZEON is a new form of a creatine which is CR bonded to a glucose polymer yielding "creatine gluconate". Creatine gluconate is a combination of creatine and gluconic acid which is said to result in better absorbtion. Although I'm not sure if it is just faster saturation which would cause the appearance of better absorption or truly better absorption. Apparently, the creatine converts to creatinine after it enters the cell of the muscle which results in less water retention for better gains in lean mass. SIZEON by Gaspari Nutrition makes a TON of claims and does so without flashy advertising showing the traditional skinny guy got big = gets babes. The claims are great but so is the science backing them up. I respect the fact that Gaspari's advertising appeals to science and reason rather than sexuality and flashiness, although at times the ads include both. But the fact is, there is something to respect about a company which openly displays the scientific research in the ads, rather than merely stating vaguely that research has been supposedly done. This is one way in which Gaspari is far more honest than MuscleTech. MuscleTech will claim that studies have been performed on their products and NEVER direct you to the study to review for themselves. I'll be honest and say that this aspect of MuscleTech really annoys me [and that is putting it lightly], and it is very relieving to see that Gaspari goes a step further to actually educate their buyers. That said, most buyers will not research the supplements they use one way or another but for someone like myself, I much prefer to research any health or fitness product that I try.

Below are some of the claims that SIZEON makes:

  • Maximizes muscle cell volume
  • Increases muscle cell ATP concentration
  • Increases the rate in which metabolic wastes such as lactic acid and ammonia are eliminated from muscle cells
  • Maximizes intracellular energy production
  • Increases oxygen and nutrient delivery to muscle cells
  • Optimizes intravascular fluid levels and flow

Rich Gaspari said he wanted to produce cutting edge supplements that work and based on my use of SIZEON in March it does exactly that. In addition, results are noticeable after only three days with 90% of the results seen after only one week. Is that crazy or what?

Below are the conclusions from a scientific study on SIZEON. I'm still researching this to determine whether or not it was a peer reviewed study or published in a non-peer reviewed database. The results:

In a clinical study published by the Ohio Research Group, using a randomized double blind design with 30 healthy men, Body weight increased in SO (+1.9%; 91.82 ± 16.99 [baseline] to 93.59 ± 17.30 kg [day 28], p<0.0002), whereas no changes were observed in AAKG (-0.7%; 82.92 ± 5.39 [baseline] to 82.33 ± 6.31 kg [day 28], p<0.25). Body weight tended to increase in CEE (+1.0%; 79.58 ± 13.31 [baseline] to 80.35 ± 12.9 kg [day 28], p<0.10). Similarly, lean mass increased in SO (+2.8%; 64.79 ± 3.84 [baseline] to 66.61 ± 3.55 kg [day 28], p<0.0001), did not change in AAKG (+0.2%; 62.38 ± 5.22 [baseline] to 62.49 ± 4.92 kg [day 28], p<0.74), and tended to increase in CEE (1.0%; 61.50 ± 5.80 [baseline] to 62.05 ± 5.83 kg [day 28], p<0.10). Additionally, there was no significant change in the percentage of body fat for those participating in the trial group. Better still was that strength increases varied directly with increases in muscle mass.

No significant changes in % fat or fat mass were noted between or within groups. All groups had significant increases in 1-RM bench press from baseline to day 28, however, no between-group changes were noted. RTF increased in SO (+28.7%; 27.2 ± 12.2 [baseline] to 35.0 ± 17.0 reps [day 28], p<0.0001), but did not change in CEE (+8.9%; 30.4 ± 13.4 [baseline] to 33.1 ± 15.9 reps [day 28], p<0.16), or AAKG (+3.7%; 21.6 ± 8.5 [baseline] to 22.4 ± 8.1 reps [day 28], p<0.51). While these results are truly amazing, the exact mechanism of HOW SIZEON yields these results is not exactly known.

To check out the research behind this clinical trial for yourself click on the link below:

This is supposed to be a non-hormonal anabolic compound but the first thing that goes through my mind is that it is obviously spiked with hormones but even dianabol or trenbolone don't have any compelling clinical trials to suggest they pack on lean muscle mass like SIZEON does. This supplement is so effective I'm even somewhat concerned that the safety has not yet been established especially given that there is no governing regulatory agency for the supplement industry. I like the results, but being a health fanatic I'm going to continue my research tomorrow in the electronic journals database at Lakehead to learn more about the safety and efficacy of this supplement.

Yes, I am serious when I say that SizeOne is THAT effective. It is roughly what I would expect from a low dose steroid cycle, which is why I seriously questioned whether or not it may contain steroids when I first used it in 2007. When I used it again in 2007 around five months later, I found that the gains were roughly the same but I put on mass slowly over the full 30 days rather than quickly and more towards the beginning of the cycle as I did my first time out. In both cases, my strength did not increase in any serious way so I would not really consider SizeOn for the purposes of building strength, but as far as doing what the name tells you - putting SIZE ON - it does exactly that and it does so extremely well.


While scanning over the ingredient details for SizeOn, nothing really jumps out at me right away. It contains 125 calories per serving which is more or less what I would expect from a product of this type, and that is from 31 grams of carbohydrates comprised of 4.7 grams of dietary fibers and 14.5 grams of sugars. It contains no protein and no fat, as you may well expect from a creatine product. SizeOn contains vitamin C, folic acid, vitamin B12, calcium, magnesium, zinc, sodium, and potassium. The 400mg of sodium might be worth pointing out since some bodybuilders try to keep their sodium levels done, but that is more common during cutting periods and I will go out on a limb here and assume that most bodybuilders are in a bulking phase if they are using SizeOn!


I have tried all three flavours of SizeOn at this point and all of them mix in exactly the same way. I drink my SizeOn in water during my workout as the instructions state [or in water shortly before bed on non-training days]. I find that it mixes very well, although it still tastes a little sandy as the SizeOn mix does not completely dissolve in water. However, if you wanted to mix it with more water it would be a little smoother but at that point it would not taste as good [it would be less sweet]. Personally I don't mind the texture at all and would expect it from any creatine powder. It is important to point out that SizeOn leaves very little clumpy parts and in fact, I can't recall any at all during this most recent 30 day course in SizeOn that I have just completed. I have no problems at all with how SizeOn mixes and I would recommend using a shaker bottle for you drinks. Before going to bed I would mix it in a glass with water using a spoon. It mixes faster in a shaker bottle of course which is why I recommend that you purchase one and bring it to the gym with you. Some people merely put the SizeOn in their mouth and drink water from the fountain to consume it, but I would recommend against that and instead use a shaker bottle and sip on the SizeOn drink throughout the course of your workout. I would rank the solubulity at 8/10 overall, but 10/10 in comparison to most other creatine/nitric oxide products that I have tried.


This time out, I tried the "Wild Berry Punch" flavour and I would rank it as intermediate between "Grape Blast" [which I used for my first experience with SizeOn] and "Arctic Lemon Ice" [which I used for my second]. I would say the berry flavour is close to grape and both are pretty comparable. I did not particularly care for the lemon flavour in comparison, but it wasn't too bad. If I were to use SizeOn again I would order the grape flavour again. It tasted a little like berry juice I suppose, and it did not really have a strong "supplement" taste, like the kind you would expect from nitric oxide supplements which always have a very distinct taste, or protein bars, which always taste like they are dense in protein. With that said, I could still obviously tell that this was not merely a juice, but rather a health supplement, but my point is that it was not particularly strong tasting. When I used SizeOn for the first time, I can honestly say that I looked forward to my daily grape drink. I did not feel as strongly about it when I tried the lemon flavour, and while I would say the berry flavour was closer to grape in terms of taste, I cannot say that I looked forward to drinking it daily to the same extent that I did when I tried grape. Overall, I would rate SizeOn berry to be an 8.5/10.


When I tried SizeOn for the first time, I had no expectations of it and expected a placebo effect, if any at all. When it worked so well, I had high expectations the second time I used it, and when it worked out great that time, I maintained my same high expectations for the third time out. I have just completed my 30 day cycle with SizeOn today [about 3.5 hours ago]. During this cycle, I found that once again SizeOn fulfilled my expectations. The two main ways in which I always found SizeOn to be effective have been in terms of putting on size and getting great pumps at the gym. The pumps were so good in fact, that they are quite comparable to the pumps achieved from nitric oxide supplements and in fact better than most of the NO products available on the market today. I find that to be the greatest advantage of non-steroidal supplements - they help to increase the pump in the gym which works as a great psychological motivation. You may think that this is only useful in the gym but it in fact carries over after the gym because I can say from my experience that the memories of an intense pump manifest in the effort I put forth towards my diet when I am out of the gym. Even if creatine products did nothing BUT boost my pumps and result in very little gains comprising mostly of water, I would STILL use them because of the psychological boost I get from those pumps. I don't use them very often but I do use them from time to time and I like the results.

In terms of mass gain, I put on 9-11 pounds using SizeOn both of the other times, but this time out I only put on around 4-6 pounds which was down from both of the previous trials. However, I was lighter when I used SizeOn the other times and so gains were perhaps a little easier at that point where I have hit somewhat of a plateau lately. I should point out that after enough time passes I find that I always lose all gains I achieve from using creatine products. I think this is because the muscle that is built in a creatine-rich environment needs a creatine-rich environment in order to be sustained. I will point out that it took at least three months to lose the gains from SizeOn both of the other times I took it and even if you use steroids, the gains will eventually be lost after enough time off from the drugs passes. So you should never expect a miracle from creatine or even from steroids for that matter. I will also point out that most of the ads for supplements that you see in the bodybuilding magazines are garbage and totally unrealistic, but the Gaspari ads are a lot more realistic in comparison - I found that the SuperPump250 ads were pushing it in terms of the supposed results that you should expect, but the SizeOn ads put the basic information out there and were pretty sound without making extraordinary promises. You should never seriously expect that supplements are going to be as effective as the advertisements would make them out to be but some are better than others and some are more realistic. As far as other ads and other creatine products go, I consider SizeOn to be the best one on the market which I have sampled so far and one which delivers very well.

Use in the Gym:

In the gym, I found that the major effect that SizeOn had was in terms of the overall quality of my pumps throughout my training. In fact, the pumps were so good that I had no reason at all to include any sort of nitric oxide supplement in addition to that. I can even say that very few nitric oxide supplements deliver the pumps to the same extent that SizeOn does and that while the Gaspari stack may consist of both SizeOn and SuperPump250, I don't even think the SuperPump250 is necessary since SizeOn is so effective alone and from my experience had no side effects to boot.

Use on Rest Days:

On rest days, I didn't notice anything particularly noteworthy regarding my use of SizeOn. I found that I felt pretty normal on those days with no major changes in my mood or my appetite. I found that the real effects of SizeOn took place in the gym in terms of the overall quality of my pumps and of course in terms of putting on mass over the course of the cycle.

For the third time using SizeOn, I found that the results were pretty well exactly the same although I did not put on as much mass this time out as I had the previous two times. The pumps were as good as they were during both of the other trials and also much like the other two trials, I experienced no noticeable gains in strength. I can bench press 225 for around 20 or so reps when I am at my strongest, and I found that I was only able to perform that lift for as much as 17 reps on average when I took SizeOn. But I should point out that I had very few days where I was feeling considerably weaker than I normally do, and every day was a pretty good one in terms of strength - just not indicative of my personal record lifts during the length of time I used SizeOn.

I do not know how long I will maintain my new gains from SizeOn, but if my previous experience is any indication, I will lose the size over the course of the next few months which is normal for any creatine product. I find that what is built in a more anabolic environment must therefore be maintained in a more anabolic environment.

Overall Review:

Overall, my experience with SizeOn for the third time has been roughly equal to both of my previous trials with the only exception being that I only put on about half the size this time out [around five pounds instead of 10 pounds]. However, I can't say that I really even noticed that and if I had to guess I would have actually guessed that I put on about the same amount of weight that I did the other two times. My strength did not go up nor did it go up when I previously used SizeOn. I found the taste of the Wild Berry Punch SizeOn to not be quite as good tasting as the Grape Blast flavour, but noticeably better than the Arctic Lemon Ice flavour. I also found that SizeOn mixed well and in addition to the above, I found there to be no side effects whatsoever. That is great considering the quality and length of time of my pumps. I even found that the pumps would carry over during the time after my workout. Whereas without using Sizeon my pump would vanish around 15 minutes after leaving the gym, I found that I would feel full much after my time in the gym was over and I even found that I would wake up in the morning feeling full rather than feeling flat as I normally do when I am not using any supplements. For the third time out, I would have to rate SizeOn to be a 9/10 and I would definitely use it again if given the opportunity. I feel that it is very high quality and can be used alone without the use of a nitric oxide supplement along with it since it delivers the stated aim of an NO supplement in addition to delivering the stated aim of a creatine supplement.

Gaspari Nutrition SuperPump250 is a supplement which I have tried before and previously reviewed. At the time I reviewed it I told myself that I would never review it again because I found the side effects to be absolutely unbearable. So much so in fact that I actually stopped using it prematurely since I could not handle them. These side effects were related to all levels of digestion of the product. I found it hard on my stomach, a cause of gas, and even diarrhea. These side effects were persistent for the entire day whether I was in the gym or not. Since the side effects were so difficult to tolerate, I wrote off ever using SuperPump250 again. I found that the product worked very well, but not as well as other nitric oxide supplements that I have used and so it was certainly not worth using again given the side effects. I considered the product to be about an 7.5/10 or so in terms of delivering pumps, but given the side effects, I could rate it no more than a 4/10 since I would be very unlikely to try it again or to use it regularly. A couple of my friends had colourfully named it "SuperDump2Shitty" due to these side effects, LOL. I have to say that overall in my life I rarely experience side effects with anything. While I have friends telling me that they have a difficult time digesting dairy products or that they experience side effects from medication and things along those lines, I find that I rarely experience any side effects with anything and in fact, I have only to my recollection had one headache in my life spontaneously and another headache when I was ill with pneumonia in 2006. Since I rarely get sick and rarely experience any sort of side effects with literally anything, the side effects from SuperPump250 were particularly noteworthy. I am certainly not the only one who have experienced these side effects and it really makes me think about what aspect of the product my body is rejecting. In any event, I decided that I would review SuperPump250 again for a second time but only using a sample pack because I was unwilling to use it for extended periods of time in fear that saturation in my system would result in the same side effects I experienced the last time I used it.

First Impression:

I decided that SuperPump250 was worth a shot and I ordered a free sample which you can order too at the links available on this page. I felt that it would be worth a try and that it would be a good addition to my SizeOn stack which I described in detail above. I thought that the sample size was nice and convenient and it would be worth a try.


Given the side effects that I experienced while previously using this product, I felt that a good place to start to try to learn about what the cause of that may be would be to look at the list of ingredients. At first, glancing over the ingredient list, things seem pretty normal. It contains only 32 calories per serving which is from 8 grams of carbohydrates. It has no protein and no fat and has 135mg of sodium which is pretty low but those on a low sodium cutting diet will likely wish to keep this fact in mind. If you check out the links on this page and view the ingredient list in greater detail, the patent pending matrices it contains are most likely the cause of the side effects although it would be difficult for me to pinpoint exactly what the mechanism for those effects are. A lot of supplements on the market today contain similar ingredients so I am not sure what about SuperPump250 is so much different to cause this effect. Please not that this product is different for everyone and that there are plenty of users who have used it who have experienced no such digestion effects from it.


I found that SuperPump250 mixed very well. I drank in in a bottle shortly before my workout and upon shaking the bottle, it was pretty smooth overall, perhaps even a little more than SizeOn was. It was smooth and only a little sandy which is what I would expect from a nitric oxide supplement. I can't complain about the solubility because it was pretty good overall and I would rate it an 8/10 in terms of solubility/texture.


I find that NO products in general do NOT taste good. They all have a distinct taste and some products are better than others at masking it. While SuperPump250 did not mask it 100%, I have tasted other NO products which are far stronger and so I can't be very hard on SuperPump250 in comparison to some of the other ones on the market. With that in mind, I do find NO products to be a little bit of a chore to swallow in general and SuperPump250 wasn't much of an exception to that rule. The taste is very hard to mask.


I only used a one day trial of SuperPump250 because I wasn't sure how my body would handle it the second time out and I felt that I could get a pretty good idea based on my one day use.

Use in the Gym:

For my workout today, I did shoulders starting off with seated dumbbell presses and followed it up with alternate arm standing dumbbell presses, seated machine presses, and side lateral raises both on the machine and using dumbbells [one arm at a time]. I normally get pretty good upper body pumps and today was no exception. I found that the pump was both consistent throughout my workout and long lasting even after my workout was over. That latter benefit is definitely one of the best things about a good NO product - you get to feel pumped even after the gym experience is complete. I can definitely say that SuperPump250 is a good NO product and did what it said it would. I would rate it around an 8/10, about how I felt it was the last time out in terms of overall quality.

Side Effects:

I was very keen to pay attention to any side effects of SuperPump250 in fear that there would be a repeat of what I experienced the last time I used it. As soon as I drank my SuperPump250 beverage I found that I experienced slight stomach pain and what appeared to be digestive issues shortly thereafter. However, this could have very well been a sort of placebo effect all on its own and with no basis in reality. Afterwards I did not experience any additional side effects and it has been around five hours at this point since I had my drink and I do not feel any side effects at this point in time, therefore I cannot state that there was any true repeat of the effects that I experienced during my first trial with SuperPump250. However, this is only based on a one day review and I cannot say for certain that I would have experienced no side effects if I had continued to take it for extended periods of time. I would have no problem using SuperPump250 sporadically but I find that when it is saturated in my system, I do experienced uncomfortable side effects which I would want to avoid. I should also point out that even though the side effects are the most salient effect, I imagine that if saturation creates side effects it also creates a positive effect which translates towards greater pumps and so I am not sure if sporadic use of this supplement is as beneficial as use over a longer duration. That said, I have no interest in trying it for extended periods of time again, but will use it from time to time during individual workouts.

Overall Review:

Overall, this time out I experienced the positive effects of SuperPump250 without the negative effects. As a result, I can wholeheartedly recommend it in that capacity and while the results of this review will not necessarily carry over to the effects of this supplement over an extended period of time, I can definitely recommend that you check out the links on this page and order the free sample and see for yourself if it is worthwhile to purchase a longer supply of this product. After all, a free sample comes at no financial risk to you and you will be able to determine whether or not it is a product you want to invest some of your hard earned money in. In terms of delivering its stated aim, SuperPump250 delivers and since I did not experience the side effects I did the firs time out, I would rate this product an 8/10 based on my one day trial.

Final Thoughts on Both Gaspari Nutrition SizeOn & SuperPump250:

Overall, I think that Gaspari Nutrition lives up to its name "The Name You Trust. The Brand That Works". I greatly enjoyed using SizeOn and loved the effects, not just this time out, but both of the other two 30-day periods in which I tried it. I did not much care for the side effects from SuperPump250 when I used it over an extended period of time but I found that using it for one day not only delivered the pump enducing effects that it promised, but also came with little to no side effects. With that in mind I consider SizeOn to be sort of a combination supplement which results in hypertrophy [mass-building] as you would expect from a creatine, but also delivers pump boosting effects which you would expect from a nitric oxide supplement. As a result, I see no reason to include SuperPump250 along with SizeOn, or any other nitric oxide supplement for that matter, since I think SizeOn is perfectly fine all by itself. That said, if you plan on ordering SizeOn, check out the links on this page and be sure to include a free sample of SuperPump250 with your order because it is worth a shot and you might just like it enough to buy a full tub at a later date. Both products are affordable with SizeOn going at a cost of $19.99 for 430 grams or $47.99 for 1290 grams and SuperPump250 going for a cost of $18.99 for 280 grams or $38.99 for 800 grams. I tried the 1290 gram SizeOn since it is a 30-day supply tub, and the 800 gram SuperPump250 which contains 40 servings and can be used simultaneously with SizeOn if you wish. Overall both of these products deliver what they say they should, but I would reward SuperPump250 an 8.5/10 while I would reward SizeOn a 9.5/10. I look forward to using SizeOn again and will likely sample SuperPump250 again in the future as well. :)
